Joint range-angle beamforming with application to estimation of targetdensity functions,

摘要

Abstract: A new technique is developed to achieve focusing in range and direction (angle) (joint range-angle beamforming) on the received signals simultaneously, transmitting one wave-beamform. It is shown how this can be utilized to estimate target density functions in the range-direction coordinates in three dimensional space. It is also shown that range-angle focusing can be achieved using only one sensor via transmitting several wave-beam forms. !10
